IMPROVEMENT IN EXTENSION-FIXTURES FOR LAMPS AND CHANDELIERS.

Specification forming part of Letters Patent No. 165,846, dated July 20,1875; application filed January 13, 1875.

To all whom it may concern Be it known that I, GEORGE R. LYON, ofChicago, in the county of Cook and State of Illinois, have invented anew and useful Extension-Fixture for Lamps and Chandeliers; and I dohereby declare that the following is a full and exact description of'thesame, reference being had to the accompanying drawings and to theletters of reference marked thereon.

The object 1 have in view is to make a fixture for chandeliers andpendent lamps, capable of being extended to any desired distance, whichwill be durable, simple, and convenient in use; and my invention thereinconsists in the means of raising and lowering the fixture,

as more fully hereinafter set forth.

To enable others skilled in the art to make and use my device, I willnow proceed to describe the same in connection with the drawings, inwhich- Figure 1 is a perspective view of my device Fig. 2, a separateview of the fixture and rod, and Fig. 3 a separate view of the sleeve.

Like letters of reference denote similar parts in each figure.

A represents a lamp or chandelier frame of anyordinary construction, towhich is attached a rod, B, the upper end a of which is bent at rightangles to the rod, and forms a short hook. 0 represents a sleeve, inwhich is inserted the rod B, made in the form of a halftube, and havinga head, I), by which the fixture is suspended. The sleeve 0 has a seriesof slots, 0, extending its entire length, to receivethe hook to on therod B. The sleeve 0 is further provided at its lower end with a collar,(1, which encircles the end of said sleeve and serves to keep the rod inthe sleeve by the hook on its end coming in contact with said collar. Drepresents a spiral spring coiling around the sleeve, and fastened byone end to the head I), and by the other to the top of the frame A,where the rod B is secured thereto.

The operation of my device is as follows: The fixture being suspendedfrom the ceiling, or from a bracket on the side wall by the head I), thehook at engages in one of the slots 0, and holds the fixture firmly inthat position. When it is desired to lower the fixture, grasp its lowerpart, and tilt it so as to disengage the hook from the slot. It can thenbe lowered to the next slot, or the whole length of the sleeve, untilthe hook strikes the collar d, when it will engage with the last slot inthe sleeve. It can be raised in the same way.

The model and drawing show my device attached to a lamp-frame, but it isequally applicable to chandeliers.

The advantages of my device are apparent. The lamp, when in use, can belowered was to cast its rays at any height, and when not in use can beraised so as to be entirely out of the way.

Having thus described myinvention, what I claim as new and desire tocover by Letters Patent, is-

The combination, with a lamp or chandelier" frame, of the rod B, havingthe hook a, and sleeve 0, having slots 0, the whole being incascd in thespiral spring D, as and for the purpose set forth.

This specification signed and witnessed this 5th day of January, 1875.

GEO. R. LYON.
